Title: Improvements in the bonding of polyester fibrous material to rubber
Inventor: CHAPMAN ROY
IPC: C08J5/06
Filed: 1964-04-09
Abstract: A composition suitable for use in the bonding of polyester fibres to rubber comprises an aqueous dispersion of a solution in an organic solvent of a partial reaction product of a polyamide and an epoxy resin.  The reactive polyamide is any polyamide having reactive amine groups spaced along the polyamide chain which result in an amine value of 80-350, the amine value being defined as the number of milligrams of sodium hydroxide equivalent to the base content of 1 gram of polyamide as determined by titration with hydrochloric acid. The epoxy resins used are glycidyl ethers of di- or polyhydroxy compounds, e.g. bis - phenols, Novolac resins and glycerol.  The organic solvent may be an alcohol, ketone, aldehyde, ethylene glycol monoethyl ether, epichlorhydrin or an unsaturated olefinic epoxide. The composition may be prepared without the use of an emulsifying or dispersing agent although one may be added.  The composition may also contain an aldehyde, e.g. furfural and formalin, and a polyvinyl chloride emulsion.ALSO:The adhesion of fibrous materials, e.g. filaments and fibres, made from polyesters derived from aromatic dicarboxylic acids, e.g. terephthalic acid and bis 4:4-carboxy phenoxythane, and a glycol, e.g. of the formula OH(CH2)nOH in which n is a whole number of 2-10, or 1,4-di(hydroxy methyl) cyclohexane, to rubber is improved by applying to them a first dip comprising an aqueous dispersion of a solution in an organic solvent of a reactive polyamide and an epoxy resin, and then a second dip comprising a resorcinol-formaldehyde-terpolymer of butadiene, styrene and vinyl pyridine latex aqueous dispersion.  The reactive polyamide used is any polyamide having reactive amine groups spaced along the polyamide chain which result in an amine value of 80-350, the amine value being defined as the number of milligrams of sodium hydroxide equivalent to the base content of 1 gram of polyamide as determined by titration with hydrochloric acid.  The epoxy resins used are glycidyl ethers of di or polyhydroxy compounds, e.g. bis-phenols, Novolac resins and glycerol.  The organic solvent may be an alcohol, ketone, aldehyde, ethylene glycol monoethyl ether, epichlorhydrin or an unsaturated olefinic epoxide.  The first dip may be prepared without the use of an emulsifying or dispersing agent although one may be added.  After the first dip the fibrous materials may be dried and cured at 180 DEG -260 DEG C for 10-100 seconds.  The second dip may be prepared by the addition of a terpolymer of butadiene, styrene and vinyl pyridine to a resorcinolformaldehyde condensate, dissolved in water.  The first dip may also contain an aldehyde, e.g. furfural and formalin, and a polyvinyl chloride emulsion.

Title: An apparatus for the feeding of cigarettes into the grouping device of cigarette packing machines
IPC: B65B19/10
Filed: 1950-06-14
Abstract: 677,372. Endless conveyers. SKODOVY ZAVODY PLZEN, NARODNI PODNIK, and BASUS, J. June 14, 1950. [June 14, 1949] No. 14859/50. Class 78 (i). In a packing machine for cigarettes or similarly shaped articles which comprises a counting or grouping device, the speed of a conveyer which feeds the articles from a supply hopper 1 to a casing containing the device is controlled in dependence upon the quantity of articles within said casing so as to maintain said quantity between predetermined limits. Cigarettes pass through a hole 20 in the base of the supply hopper 1 the feed being controlledby an adjustable trimming wheel 21 which spreads them on endless belt 3 driven by a motor 8. The cigarettes are discharged from belt 3 into casing 11 where they fall into grouping channels 12 for feeding the packing machine. A plate 13 within the casing is mounted on a shaft 14 which carries outside the casing a mercury switch 15 consisting of an arcuate tube having three contacts 16, 17 and 18. Plate 13 rests against the cigarettes as they flow into the chamber. With the packing machine working at full capacity, as illustrated, contacts 16 and 17 are joined by the mercury, these completing an electric circuit to the motor 8 so that it runs at high speed. When the packing machine cannot cope with the supply of cigarettes plate 13 is pushed away from the end of the conveyer belt which causes the mercury to join contacts 16, 18. This also completes a circuit to motor 8 but through a resistance so reducing the speed of belt 3. If the packing machine stops the accumulation of cigarettes moves the mercury onto contact 18 only thus stopping the motor. If, with the packing machine working to capacity the supply of cigarettes from hopper 1 stops or is small the mercury moves onto contact 17 only thus also stopping the motor, this indicating either that hopper 1 is empty or that the position of trimmer 21 needs adjusting.

Title: Improvements in or relating to fractional distillation
Inventor: HARDING ANTHONY JOHN
IPC: B01D3/14
Filed: 1959-05-01
Abstract: In a fractional distillation process, vapour <PICT:0870307/III/1> removed from a distillation column is used completely or partially to vaporize liquid feed by indirect heat exchange in a vaporizer, and the vaporized feed produced thereby is compressed and then introduced as vapour at an intermediate point of the column, the column being operated at a pressure higher than that in the vaporizer.  Preferably the pressure in the column is such that the temperature, and condensation temperature, of vapour removed from the column are high enough to effect at least partial vaporization of the liquid feed without the vapour being thermo-compressed. The vaporized feed is preferably compressed adiabatically to conserve the heat of compression.  Vapour used to heat the vaporizer is preferably completely condensed and part of the condensate returned to the column and used as reflux while the remainder is removed as final product.  Alternatively all the condensed vapour may be returned to the column and refined product taken from the top of the column. Although all the liquid feed may be vaporized in the vaporizer, part of the feed from the vaporizer may be fed instead as liquid into the distillation column.  As applied to the distillation of crude methanol the process comprises completely vaporizing the crude methanol feed in a vaporizer 1, compressing the vapour by a pump 2 and feeding it to a distillation column 3.  Reboiler 4, which is heated by steam, supplies heat to the column.  Pure methanol is removed from the top of the column and heavy ends are purged from the bottom. Overhead vapour from the column passes through the vaporizer, whence both condensate and uncondensed vapour are passed to a condenser 5 from which condensate is pumped via a drum 6 back to the column as reflux.

Golf-practising appliances. - In apparatus for practising or playing a game and comprising a tee having two positions, in the lower of which it is supplied with a ball, the tee may be depressed by the player against the action of means urging the tee into its normal higher position. The tee f projects upwardly through an aperture d in a casing b and is carried at the free end of an arm g mounted on a pivot h. The arm g may be depressed against the action of a spring q by the application of the club head to a part n of the arm that is disposed within an aperture e in the casing. In the lower position of the arm, the balls stored in a sloping magazine s roll downwardly until arrested by stops u. Upon release of the arm, the tee rises, carrying with it the foremost ball in the magazine. A projection k on the arm maintains the balls in position while the tee is in raised position. The tee is formed of soft rubber and is secured to a. spigot i of harder rubber disposed below the level of thecasing. The height of the tee is adjusted by a screw m on the arm, and the strength of the spring q is varied by altering the effective length of the screw p by which the spring is connected to the arm. A rubber mat w is let into theuppar surface of the casing for protective purposes. In the event of the balls being driven from the tee into a net, they may be pulled back into a hole c communicating with the magazine. In a modification, the magazine is arranged at right-angles to the arm, and the arm is returned. to its normal position by a counterweight.
